I think there are some issues with using the newer radios on cars with older CAN BUS controllers. You may need to upgrade that... THere are a lot of posts around (not just in here) about these issues, but I am not knowledgeable enough on the subject to be able to definitively state that is the issue...

Yes it could be problem somewhere there...
I do have curent vag com but dont know what i need to do( or do i need ) do i need some coding to be done in can bus or in the radio...

Using your VAGCOM find out the part number of your CANBUS controller (Controller 19 I think)...
